GRIDDLE.

Specification of Letters Patent No. 30,028, dated September 11, 1860.

To all whom it may concern:

Be it known that I, GEORGE W. PITTOOK, of Union Mills, in the county ofFulton and State of New York, have invented a new and Improved Cake-Griddle; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon.

The nature of my invention consists in so constructing and arrangingarms or cross pieces in connection with a tube or circular ringhereinafter described, so as to form a center or axis, all of whichshall contract and expand in equal proportion to the ex pansion andcontraction of the said tube or circular ring and allow any rotating topto easily revolve thereon as well as to prevent the breaking of eitherof the said arms or cross pieces or any part of the said ring asotherwise would be the case-by reason of an unequal contraction andexpansion; also to prevent friction.

I construct my cake griddle with a tube or circular ring as shown at(B), Fig. 1. The lower edge (5) of this ring rests upon the top of thestove, while the upper edge (a) is immediately below, and nearly inconnection with the under side of the rotating top (D), as seen at ((Z)same figure. This ring may extend upward to any desired height and maybe of any required thickness. Upon the inside of this ring '1 constructarms or cross pieces as seen at (A), Fig.

, 3, which unite at (0) and form a center or axis for the rotating top(D), Figs. 1, and 2, to bear and rotate upon. The said arms or crosspieces are constructed each with an arc of any required size, as shownat (f), Fig. 3. This is for the purpose of prevent ing the said arms orcross pieces from breaking by reason of the expansion and contrac tionof the tube or ring (B) it having about three times of the contractingand expanding surface of perfectly straight arms or cross piecesextending from one side of said ring to the other side thereof andthrough the center. These arms or cross pieces thus constructed each inthe form of an arc, and being between the inside of said ring (B) andthe center of the same, as shown at Fig. 3, of the drawings, willcontract and expand in proportion to the contraction and expansion ofthe said ring (B) and thus prevent any part from breaking by reasonthereof. )Vere they straight across, their contraction and expansionwould only be about one third as much as that of the said rings (B),consequently would break and of course be useless. Upon the uppersurface of the said arms or cross pieces (A) and near to the axis (0)Fig. 3, I construct a small ring or circle (R, B). This is for thepurpose of keeping the rotating top in a horizontal position with thesaid ring (B), also to prevent friction by preventing the outside partof the rotating top (D) from coming in contact with the upper edge ofthe tube or ring (B) as shown at (d), Fig. 1. This ring or circle (R, B)being near the center of the griddle of course has much less frictionsurface than it would have did it bear or rest upon the upper edge ofthe said tube or ring By this arrangement to prevent friction, the saidrotating top (D) will more easily revolve or turn upon its centralbearing. In this respect, this griddle has an advantage over the griddlepatented to Bauford Grilbert Oct. 11th 1853. I need not describe theoperation of this griddle for cooking purposes, as that may well beunderstood upon examination of the article.

I do not claim the formation of hot air chambers upon the top of stoves,nor do I claim the rotating of the griddle top but )Vhat I claim, anddesire to secure by Letters Patent, is

The combination of the arms or cross pieces (A) with the inner ring (R,R) and the tube or ring (B), as and for the purposes herein describedand set forth.

-GEORGE W. PITTOOK.
